Patent JP-H08322057-A (JP)
Title: Convergence circuit
Inventor: IIJIMA MINORU
IPC: H04N9/28
Filed: 1995-05-24
Abstract: PURPOSE: To provide a convergence circuit which can correct the convergence without causing any distortion on a screen at the dividing points by dividing a multiplication waveform of both horizontal and vertical sawtooth waveforms into the half of a vertical scanning period by a DC clamping circuit that uses the diodes. CONSTITUTION: The DC bias is applied a diode D1 and the anode voltage of the diode D1 is clamped at 0.7V. When a multiplication waveform is inputted to the diode D1, the cathode of a diode D2 is clamped at 0V lower than the anode voltage of the diode D1 by 0.7V since the anode voltage of the diode D1 is clamped. When a vertical sawtooth waveform is inputted, the cathode voltage of the diode D2 is continuously kept at 0V in the first half or scanning and then adversely biased against the diode D1 in the latter half of scanning. Then the divided waveforms are outputted to the cathode of the diode D2. Under such conditions, the dividing points smoothly change and no discontinuous points are produced even if the phases of zero cross points are shifted between the vertical sawtooth waveform and the multiplication waveform.

Abstract: PURPOSE:To obtain a stable cleaning effect on a head and a rotary drum for a long time by supporting a cylindrical sponge by a ball bearing to a lever shaft in a position of a boundary part between the rotary drum and a fixed drum. CONSTITUTION:A shaft 7 which is parallel to an axial center of a head drum 1 is provided at one end of a lever 5 which is freely rotatable, and in the boundary part between the rotary drum 11 and the fixed drum 12 which constitute the head drum 1, the cylindrical sponge 8 is supported via one ball bearing 13 at the shaft 7, and this sponge 8 is constituted to be abutted against the rotary drum 11 and fixed drum 12. That is, the sponge 8 can be in pressurized contact with the rotary drum 11 and the fixed drum 12 by force of uniformity owing to the aligning function of the ball bearing 13. By this method, even in case of the sponge 8 being poor in cylindricity and bad in parallel with the shaft 7, and moreover even when the sponge 8 is changed with time, the stable cleaning effect can be obtained for the head and the rotary drum 11 over a long period of time.

Title: Scroll type compressor
Inventor: UCHIDA KAZUHIDE
IPC: F04C18/02
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To surely prevent the abrasion of the thrust load support face of a scroll type compressor by an inexpensive means. SOLUTION: A groove part 6d is provided on the circumference of the back face of an end plate part 6b being one of supporting faces for thrust load acting on a movable scroll 6, and pressurized fluid is led through a communicating hole 6e which pierces the end plate part 6b from a high pressure working chamber 8a in a central part to the groove part 6d for attaining the shortest distance, and a back pressure space is formed between the flat end face part 3a of a front housing 3 being the other side of the support face and the groove part 6d to support the thrust load of the movable scroll 6. Since pressurized fluid in the groove part 6d turns into a thin film and flows out into a suction chamber 7f, a low friction thrust load supporting means supported floatingly on the fluid is therefore realized.

Title: Cooling fan driving device
Inventor: ITOU TOSHIMITSU
IPC: F01P7/08
Filed: 1978-10-13
Abstract: PURPOSE: To completely stop the revolution of a cooling fan while the temperature of an engine is low by providing a means for controlling an electromagnetic clutch according to the variation of the temperature of the engine.  
     CONSTITUTION: An electromagnetic clutch 8 is consisted of a stationary member fixed to an engine body 2, a coil 9 disposed in a concavity of the flange of a pulley 5 and a clutch plate 11 fixed to the flange of a pulley 3 by a spring 10 with a fixed gap between the flange of the pulley 5. Until the engine is properly warmed-up, a water temperature switch 28 remains opened, therefore, the coil 9 is not excited so that the electromagnetic clutch 28 remains released. As the water temperature becomes above a fixed temperature, the water temperature switch 28 closes to excite the coil 9, then the clutch plate 11 is attracted by the coil 9 against the pulling force of the spring 10 and engages with the flange of the pully 5 thus transmitting the power of the crank shaft 1 to a colling fan 22.

IPC: C02F1/22
Filed: 1989-05-18
Abstract: PURPOSE:To automatically produce the pure water suitable for drinking and to execute the process after resetting of a power source in the event of a current interruption by providing a switching device for a discharging state in which the water in a water storage tank is discharged and a water taking state in which the pure water by melting ice is taken out of the water storage tank and a controller which switches the switching device to the discharging state when the power source is reset in the even of the current interruption. CONSTITUTION:While water 34 supplied to the water storage tank 12 from a water inlet 13 is kept stirred by a stirrer 17, the water is cooled by the cold air flowing in a cold air passage 24 to form pure water ice 35 without contg. impurities. The remaining water contg. the impurities is discharged from a pipe 28 for discharging by setting the switching device 26 at the discharging state and thereafter, the ice 35 is melted by a heater 16. The pure water suitable for drinking without contg. the impurities is automatically formed when the melted pure water is taken out of a pipe 29 for water taking by switching the switching device 26 to the water taking state. Further, the trouble that the water feeding is executed and the water flows over the water storage tank 1 is prevented if the switching device 26 is switched to the discharging state by the controller when the power source is reset if there is the current interruption in the forming process of the pure water.

Abstract: PURPOSE:To make simplification in structure and controlling facilitation both attainable as well as to aim at the promotion of low-unit cost of production, by transferring a carriage fitted with a chucking member at the specified pitch, carrying in each product at the specified pitch too, while carrying out disposed parts in regular sequence. CONSTITUTION:A cylinder A of a driving source 4 operates and a feed shaft 1A is made to go forward at the specified stroke, while a cylinder 4B operates in the reverse direction, making a feed shaft 1B go back. In this case, when a fluid is fed to a cylinder chamber of a cylinder 7 and opened to the atmosphere, a pressure member is forcibly made contact with a circumferential surface of the feed shaft 1A with pressure whereby a carriage 5 is locked to the shaft 1A by a carriage locking mechanism 6 and goes forward as far as a pitch equivalent to a forward stroke of the cylinder 4A. Next, like wise the carriage 5 is locked to the feed shaft 1B and goes back as far as a pitch equivalent to the stroke of the cylinder 4B. Thus, in the case where each product is carried in a housing case at the specified pitch or disposed parts are carried out of the case, a chucking member is transferrable at the specified pitch and structural simplification is attainable.
